STEPHEN D. MURRAY, OF DALLAS, TEXAS.

COTTON-GIN.

Specification of Letters Patent.

Application led February 4, 1915. Serial No. 6,115.

To all whom 'it may concern:

Be it known that I, STEPHEN D. MURRAY, a citizen of the United States, residing at Dallas, in the county of Dallas and State of 5 Texas, have invented new and useful Improvements in Cotton-Gins, of which the following is a specification.

This invention relates to an improvement in cotton gins and has particular reference to the mote plate and also to the Wind guard, the primary object of the invention being to provide simple and effective means whereby the mote plate may be readily and easily adjusted through the medium of a simple construction and arrangement of parts.

A further object of the invention ris to provide means for giving the mote plate a strong support and at the same time set up a tight joint or closure relatively to the lower portion thereof and a conveying tube embodied in the gin organization and extending along the brush cylinder beneath the latter and thereby to cause the air currents laden with cotton removed from the saw cylinders to be regularly directed into the A still further object of the invention is to provide simple means for adjustably mounting the rear wind guard on a portion of the cotton conveying tube -and equip the said guard with means for readily adjusting the same.

l/Vith these and other objects and advantages in view the invention consists in the preferred construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawings: Figure 1 is a transverse vertical section through a portion of` a cotton gin showing the improvements applied thereto, sufcient of the operating elements ofthe gin being illustrated to demonstrate the practicability of the improvements. Fig. 2 is a front elevation of a gin having a portion thereof broken away to show the improved mote plate in its applied position. Fig. 3 is a detail perspective view of one end of the improved mote plate. Fig. 4 is a detail View of onek of the brackets with which 9 the mote plate is adjustably associated.

The improved gin is of the well known 'l type embodying a longitudinal hollow member or tube within the body of the gin, as disclosed for instance by my Patent No.

1,089,255, dated March 3, 1914, and comprises a frame 5 in which is mounted a roll box 6, a saw cylinler 7, a brush cylinder 8 arranged and operating in the usual manner, and a lint receiving tube or hollow member 9 disposed under the brush cylinder.

This class of gins Vmay be equipped with a hulling attachment or not, as may be desired. The tube or hollow member 9 has a top inlet opening 10 directly under the brush cylinder 8; and disposed in the said opening 10 is a chute 11 which is arranged at an inward angle of inclination and projects into the upper portion of the said tube or hollow member 9. The chute 11 embodies a bottom plate 12 which is extended outwardly from the forward edge of the open- .ing 10 at an upward angle of inclination and is secured to the upper part of the body of the tube or hollow member 9 adjacent to the said front edge of angular plate 13 having its two members respectively secured by bolts or fastenings 14 to the forwardly and upwardly extended portion of the plate 12 andthe adjacent part of the body of the tube or hollow member 9, as clearly shown by Fig. 1. The plate 12 terminates or continues in an obtuse angular supporting memberl which projects upwardly toward the saw cylinder 7 and is of such width as to reliably hold-a mote board or plate 16 between theends of the latter.

and approximately from the inner surfaces theopening 10 by an The plate 12 extends longitudi- Y nally along the full length of the cylinderV of the end supports 17 comprised in the 20 is a lug or boss 21. The opposite eXtrem'i-f ties of the mote plate 16 project through and are movable in the slots 18, the said slots being long enough to compensate for the adjustment of the mote plate either upwardly or downwardly to a maximum extent. The opposite extremities of the mote plate 16 extending through the slots 13 to the exterior of the gin movably bear on the flanges 20, as clearly shown by Fig. 5, and in each mote plate extremity a slot 23 is formed and extends fully therethrough, the said slots 23 both having the same angle of inclination and in the same position relatively to the opposite extremities of the mote plate. The Vslots 23 in. the opposite extremities of the mote plate are inclined upwardly or are in diagonal planes relatively to the mote plate extremities, and the lugs 21 movably engage said slots and extend entirely through the same. The adjustment of the mote plate is accomplished by any suitable tool that may be used to give the said plate a longitudinal shifting movement and operatively applied to either extremity of the plate, and a preferred form of such tool is a bar 24: having a reduced end 25 and a handle 26, as shown by Fig. 8. To render the use of the tool shown by Fig. 8, or any other analogous tool, practical in adjusting the mote plate 16, the latter has an upper opening 2T in each extremity, and the pointed end of the tool 25 is inserted in either opening in accordance with the desired direction of movement and adjustment of the mote plate 16 and pressed against a portion of the adjacent end support 17 so as to provide sufficient leverage for adjust-I ment of the mote plate. The mote plate is frictionally held in its adjusted position without the use of fastening devices. llVhen the mote plate 16 is adjusted it moves equally at opposite ends in view of the similar angle of the slots 23 and the corresponding angle of the lugs or bosses 21 projecting rearwardly from the flanges 2O of the brackets 19, and it will be impossible for the opposite extremities of the mote plate to shift irregularly for the reason that the opposite side edges of the lugs or bosses 21 closely engage the opposite side walls of the slots 23 and maintain a uniformity of movementat both extremities of the plate. The mote plate 16 is preferably made of a doubled piece of sheet metal of suitable thickness and proper dimensions bent into U-shape, the bent portion or top edge 22 being uppermost and the two free edges 28 being at the bottom, The side members of the plate are held spaced apart by interposed space members 31 positioned at the lower corners and secured by suitable fastenings 32, as clearly shown by Fig. 3. This formation of the plate 16 results in a rigid structure, and the lower edge of the plate 16 within the body of the gin is fully open between the edges 28 to permit thel angular position as the slots 18 and flanges 20 of the brackets 19. The mote plate 16 is slidable on the support 15 during its adljustment, and the support 15 adds its strength and rigidity to the mote plate or board, the two vstructures or the support 15 and bent plate 16 providing a thin yet stiff structure for the purpose specified. The mote plate 16 is adjusted relatively to the saw cylinder for a purpose which will be understood. As the outward extension of the plate 12 from the front edge of the opening 1() of the tube or hollow member 9 completely closes the space between the tube and the'mote plate adjacent to the lower portion of the brush cylinder 8, the only vent means will be at the top edge 22of the mote plate 16. It will also beseen that the mote plate 16 m-ay be readily detached from the gin and easily replaced inoperative position as occasion may require in disorganizing or in organizing the several parts of the gin.

At the rear edge of the opening 10 .in the upper portion of the tube or hollow member 9, a wind guard or shield 33 is mounted, and consists of a doubled sheet metal plate of suitable thickness having lower` rear extremities 34 bent to-conform to the curvature of the rear edge portion of the opening 10 so as to embrace the adjacent edge portion of the tube 9, the main body of the wind guard or shield 33 projecting upwardly from the lower extremities 34 at an angle to the latter, as clearly shown byFigs. 1 and 7, and

having the free edge thereof terminating close to the lower rear portion ofI the brush cylinder 8 and extending a considerable distance over the chute 11 below and particularly at the point where the chute enters at an angle to the upper portion of the tube or hollow member 9. The .guard or shield 33 is slidably adjustable relatively to the portion of the tubeor hollow member 9 which it engages, the said tube or hollow member being formed with elongated slots 35 at intervals and engaged by clamping bolts and .their necessary accessories 36 which also pass through openings 37 in intermediate portions of the lower extremities 34 of the guard or shield. By this means the guard or shield may be shifted forwardly or rearwardly to modify the distance of the upperfree edge thereof relatively to the brush cylinder.

The direction of movement of the brush cylinder 8 drives the air laden with the lint removed from the saw cylinder 7 downwardly into the tube or hollow member 9 through the chute 11, and the force i'mparted to the air currents laden with the lint causes the currents and the lint to whirl rapidly around the inside of the tube and impinge against the lowerside of the chute and again mingle with the incoming air currents Vand lint, and the two portions of the air currents carrying the lint mingling at the inner lower extremity of the chute lend their force to each other and result in an effective transmitting action or movement thereof longitudinally along the tube or hollow member 9. This operation is largely due to the extension of the chute downwardly into the tube or hollow member 9 as shown, and the disposition of the chute at a downward angle below the inlet opening 10 is also effective in preventing the lint delivered into the tube or hollow member' 9 from being drawn upwardlyy by and passing around with the brush cylinder, and the wind guard or shield 33 also materially obstructs any tendency of the cotton to pass over the opening l0 and upwardly and around with the brush cylinder 8, and, furthermore, said wind guard or shield breaks up any eddy currents at the rear portion of the brush cylinder that might otherwise be established. When this mote plate is properly adjusted, the motes as they are separated from the saw teeth by the brush cylinder will fall past the outer portion of the upper edge 22 of said plate and will not be carried along with the lint cotton to the chute 1l and into the tube or hollow member 9. The lint cotton delivered into the tube or hollow member 9 is conveyed sisting of the novel form of adjustable mote plate and wind guard or shield will greatly add to the practical operation of the gin in effectively performing its ginning operation.
